Frequently Asked Questions
Why does my Discovery 4 / LR4 air suspension keep sagging overnight?
Overnight sag on the L319 is most often caused by a leaking air spring bladder or a failed compressor check valve allowing pressure to bleed back. The manual details leak-down test procedures, compressor output specifications, and step-by-step air spring replacement for all four corners, including the required height sensor recalibration afterward.
Is the North American LR4 the same as the Discovery 4 in this manual?
Yes. The LR4 is simply the North American market name for the Discovery 4 L319 Series IV. The chassis, powertrains, and electrical architecture are identical, so all procedures, torque values, and wiring diagrams in this manual apply directly to US- and Canadian-market LR4 vehicles from 2009 to 2012.
Does the manual cover the 5.0L V8 engine in full detail?
Yes. The 5.0L AJ133 V8 petrol engine is fully covered, including top-end and bottom-end assembly procedures, timing chain service, fuel injection system diagnostics, and emissions system maintenance. Complete torque specifications and special tooling requirements are listed for every major fastener.
